The layer of the Earth made up of rocks like basalt and granite is the crust.

Here's a breakdown:

* Basalt is a dark-colored, fine-grained volcanic rock found in oceanic crust.

* Granite is a light-colored, coarse-grained igneous rock found in continental crust.

While there are other types of rocks in the crust, basalt and granite are among the most common and representative of the two main types of crust.
